5. Using the jig [1] included on the drum unit cover,

rotate the drum clockwise and confirm that there

are no gaps in the setting powder coat, and that

the toner collection sheet and cleaning blade

are smooth, etc.

6. Finish installation by reversing the sequence of

the removal procedure.

Note:

• Before installing the drum and cleaning blade

(regardless of whether new or used), be sure to

coat these with setting powder. Apply the powder

around the entire drum, and on both sides of the

blade.

• If you have coated setting powder onto the drum:

Before installing the drum unit back into the main

body, use an alcohol-soaked cloth to remove

stray powder from the sensor surface on the

toner control sensor board. This is necessary to

ensure that accurate toner density readings are

obtained.

• Be sure that the drum is oriented correctly before

installing it. The drum should be positioned so

that the convex end of the longer section comes

at the back.

• After installing a new drum, be sure to reset the

drum-related counters in the 36 mode.
